Check Digit Verification of cas no
The CAS Registry Mumber 133071-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133071-04:
(8*1)+(7*3)+(6*3)+(5*0)+(4*7)+(3*1)+(2*0)+(1*4)=82
82 % 10 = 2
So 133071-04-2 is a valid CAS Registry Number.

From Fourfold Functionalized Cyclophanes to Tube-Shaped Molecules
Schroeder, Axel,Karbach, Detlef,Guether, Ralf,Voegtle, Fritz
, p. 1881 - 1888 (2007/10/02)
A series of fourfold functionalized 2,11-dithia- and 2,11-diazacyclophanes 15-17 and 18-22, resp., is prepared by using a new multistep-strategy starting from 7 of m-xylene, respectively.The cyclophanes are used to construct tube-shaped molecules of
